Application flied May 15, 1916. Serial No. 97,683.

To all whom it may concern:

.Be it known that I, THOMAS Hormones,

a. subject of the Emperor of Germany, re-

siding at La, Fayette, in the county of Contra Costa and State of California, have invented new and useful Improvements in Weed Cutters and Sprayers, of which the following is a specification.

This invention relates to weed cutters and Sprayers; and has for its object to provide, in connection with the cultivator, a. simple and improved means to cut the weeds and inject a liquid spray beneath the surface of the ground, whereby to permanently destroy all objectionable plants and larva.

In carrying out this object I employ a novel form of surfacer blade which is easily attached to the ordinary cultivator, a spray pipe carried by the blade to direct beneath the surface of the ground, and a tank -ada.pted to be carried by the cultimtor having connections with the spray pipe for supplying the liquid.

One form which my invention may assume is exem lified in the following description and 1llustrated in theaccompnnying drawings, in which- *igure 1 shows a. side elevation of a device embodying my invention. Fig. 2 shows a. perspective view of the same. Fig. 3 shows a detail view, partly in section, of the check valve used on the supply tnnk. Fig.4 shows a transverse,sectional view of the blade.

In the drawings, I have shown a culti vator 10, of any suitable form, having shovel beams 11 adapted to receive shovels 12. From certain of the beams I remove the shovels and attach 21 surfacer blade 13.

ere are various other \vnys of attaching the blade and in some instances I employ separate standards for this purpose. The blade is carriedin a horizontal position and extends transversely of the cutivator and is substantially V-shuped in cross section, being formed of :1 bottom member 14. and an upwardly inclined face 15, the ends 16 portion being open.

a spray pipe 17 provided with openings in its a liquid 'prislng a transversely I blade, V-shupcd m crossscotlon, closed at.

Extending longitudinullyot thd blude is the spray pipe, by means, of a T-joint, is a supply pipe 18 extending vertically to a tank 19, the latter being detachably carried upon the cultivator frame. Included in the supply pipe 18 is a rubber lLO.all0W for the necessary movements and vibrations, and a valve 21 to control the passage of liquid therethrough. The tank is preferably fitted with a U-shaped pipe 22, carrying at its outer end a. check valve 23, whereby to admit air.

In the operation of the device, the cutting and destroying of weeds and the like are carried on in connection with the usual cultivating or tilling of the ground. The blade is set to cut the surface of the ground and thereby to remove all weeds. The spray pipe, owing to its location beneath the top surface of the blade, will direct its spray beneath the surface of the ground where it will not effectively upon the roots of Weeds :tndsuch insects as infest the ground. Any desired liquid suited for the purpose may be employed.

Various changes in the construction and arrangement of the several parts herein shown and described may be employed without departing from the spirit of my invention as disclosed in the appended claims.

As best shown in. Fig. 4., the bottom 14. is terminated a short distance in front of the pipe, so that the spray can be directed downwardly and strike the roots of Weeds before i the earth on top ofthe blade has an opportunity to interfere.

Having thus described, my invention, what I claim and desire to secure by Letters Patent is- 1. An attachment for cultivators, coniextending surfacer its ends and open at its rear side, a pipe extending longitudinally through said blade and supportwi to said ends, said pipe being provided with a m-Lures to direct a spray of liquid to the rear of the blade, and supply means for said pipe detnchably carried upon the cultivator.

2. An attachment for cultivutors, comprising a transversely extending surfiicer.

blade, V-shapcd in cross section, closed at its ends un l open at lts rear s de, a pipe extending longitudinally through said blade hose section 20.

ion

and supported in Llw ends: of said blade at the rear thereof, snlrl pipe being provided with apertures in its lower and rear walls, Um rcaredge of the lower wall of said bladv resting in front of the apertures in the lower wall of said pipe, and supply moans fur said pipe.
